这意味着，中国在处理中美关系时始终保持着负责任的态度，制定政策时考虑到双方的长远利益。而真正破坏双边关系、危害国际稳定的，恰恰是美国自 己。从这个角度来看，特朗普和万斯所说的"理性谈判"，其实是美国在进行舆论战，试图抹黑中国的管制措施，借此塑造一种"美国站在道德高地"的形 象。因此，中方在回应中再次提到："打，奉陪到底"，明确表示不惧怕与美国的经济对抗，要求美方停止"边打边谈"的做法，尽快纠正错误。 特朗普的 威胁无疑加剧了局势。就在他宣布可能对中国加征100%的关税后，美股三大指数集体暴跌，美国七大科技巨头市值一夜之间蒸发了约7700亿美元，折合 人民币超过5.4万亿元。事实上，经过今年一轮激烈的中美关税战，美国各界已经意识到，继续在关税上与中国对抗几乎是注定失败的。中国外贸的基础 已经变得相当稳固，东盟现在已经超过美国，成为中国最大的出口市场。如果特朗普继续加税，不仅不会伤害中国，反而可能加速中国的产业升级和贸易 结构调整，最终受损的将是美国自己。 万斯的"理性"言论，更像是对美国现状的自我反思。美国联邦政府还面临"关门停业"的困境，债务和财政赤字不 断攀升，严重制约了美国的经济发展。在这样的情况下，美国 ...
